Why Is My Dog Sleeping More Than Usual?

Dogs love to sleep, and depending on their age, breed, and activity level, they may spend anywhere from 12 to 18 hours a day resting. However, if your dog suddenly starts sleeping significantly more than usual, it's natural to wonder whether something is wrong.

While extra sleep can sometimes be harmless, it may also be a sign that your dog is experiencing discomfort, illness, stress, or an underlying health condition.

Understanding the possible causes can help you determine when extra rest is normal and when veterinary attention may be needed.

How Much Sleep Is Normal for Dogs?

Sleep requirements vary depending on age and lifestyle.

Puppies

Puppies often sleep.

• 18–20 hours per day

Growing bodies need extra rest for development.

Adult Dogs

Most healthy adults sleep.

• 12–14 hours daily

Active dogs may sleep less, while less active dogs may sleep more.

Senior Dogs

Older dogs often require:

• 14–18 hours daily

Ageing naturally slows metabolism and energy levels.

Common Reasons Dogs Sleep More Than Usual

1. Aging

One of the most common reasons for increased sleep is simply getting older.

Senior dogs often:

• Tire more easily

• Recover more slowly after activity

• Prefer longer rest periods

Gradual increases in sleep are generally normal as dogs age.

2. Increased Physical Activity

After a particularly active day, dogs may need additional sleep to recover.

Examples include:

• Long walks

• Hiking trips

• Play sessions

• Travel

Temporary increases in sleep after exercise are usually not concerning.

3. Weather Changes

Hot weather can reduce activity levels and encourage dogs to rest more frequently.

Many dogs naturally become less active during:

• Summer heat

• Rainy days

• Extreme weather conditions

4. Boredom

Dogs lacking mental stimulation or exercise may spend more time sleeping simply because they have little else to do.

Signs of boredom include:

• Excessive sleeping

• Lack of interest in activities

• Reduced enthusiasm

• Restlessness when awake

5. Stress or Emotional Changes

Changes in routine or environment can affect a dog's behaviour and energy levels.

Examples include:

• Moving homes

• New family members

• Loss of a companion animal

• Changes in daily schedule

Some dogs respond by sleeping more than usual.

Medical Conditions That Can Cause Excessive Sleep

Arthritis and Joint Pain

Dogs experiencing discomfort often sleep more because movement becomes difficult.

Additional signs include:

• Limping

• Stiffness

• Difficulty standing

• Reluctance to exercise

Infections

The body naturally requires more rest when fighting illness.

Symptoms may include:

• Fever

• Loss of appetite

• Fatigue

• Reduced activity

Hypothyroidism

An underactive thyroid gland can cause:

• Increased sleeping

• Weight gain

• Lethargy

• Poor coat condition

Heart Disease

Dogs with heart problems may tire more easily and sleep longer due to reduced stamina.

Diabetes

Increased sleeping can occur alongside:

• Increased thirst

• Frequent urination

• Weight loss

• Changes in appetite

Warning Signs That Require Veterinary Attention

Contact your veterinarian if excessive sleeping is accompanied by:

🚩 Loss of appetite

🚩 Weight loss

🚩 Vomiting

🚩 Diarrhea

🚩 Difficulty breathing

🚩 Limping

🚩 Increased thirst

🚩 Behavioral changes

🚩 Sudden lethargy

These symptoms may indicate an underlying health issue requiring medical evaluation.

How Veterinarians Diagnose Excessive Sleepiness

Your veterinarian may recommend the following:

• Physical examination

• Blood testing

• Urinalysis

• Thyroid testing

• X-rays

• Cardiac evaluation

Diagnostic testing helps identify possible medical causes.

Can Nutrition Affect Energy Levels?

Absolutely.

A balanced diet provides the nutrients needed to support the following:

• Energy production

• Muscle function

• Immune health

• Healthy aging

• Overall wellness

Poor nutrition may contribute to low energy levels and reduced vitality.

Can Multivitamins Support Daily Wellness?

Many dog owners choose high-quality multivitamin supplements to help support overall health.

Essential vitamins and minerals may contribute to:

• Healthy metabolism

• Immune support

• Energy production

• Joint health

• Healthy aging

Products such as Wag Tales Dog Multivitamins can help support your dog's nutritional needs as part of a complete wellness routine.

Final Thoughts

While dogs naturally spend much of their day sleeping, significant changes in sleep habits should never be ignored. Ageing, weather, exercise, and boredom may all contribute to increased sleep, but excessive sleeping can also signal pain, illness, or underlying medical conditions.

By paying attention to your dog's behaviour and maintaining proper nutrition and preventive care, you can help ensure they remain healthy, active, and happy throughout every stage of life.
